Fields of Application

The device has been designed for the detection of defects at tubes as well as at domestic and laboratory glass.

Tasks

• Detection of visual defects, such as bubbles, stones, knots, air lines
• Graphic display of the frequency distribution of defects
• Automatic selection of articles having too large defects

Structure and Measuring Principle

The article to be tested is moved between an illumination unit and a CCD-row camera. The images are evaluated in an image processing computer. If hollow glass is concerned, the device can be placed beside the production line. The articles to be tested are taken from the conveyor belt, fixed and rotated in front of the camera. At tubing lines two cameras at least are used which check the tube continuously.

Evaluation

The test results are transferred to a main computer. By means of a real-time and multitask software the trends of the frequency distribution are displayed. In this way the operating personnel will get a fast and concentrated survey about the test results.

Parameters

• CCD row sensor: 2048 pixels
• Testing frequency: 5000 scans/second
• Minimum size of defects: < 1.0 mm
• Display of test results frequency distribution
• Interface: RS 232
• Main computer: Pentium
• Visualization software: P-CIM

Advantages

• objective control, without human errors
• no selecting personnel
• 100% control
• high degree of selection
